IMPROVEMENT IN CHEMICAL HOT-AIR OR VAPOR BATHS.

Specification forming part-of Letters Patent N o. 173,654, dated February 15, 1876; application tiled October 1e, 1875.

baths, so that the vapors which accumulate can be removed by a cloth, and not be absorbed by porous substances, and thereby render the bath unfit for successive use.V

, It consists, mainly, in the employment ot' a rectangular case, constructed 'of glass, and

having a perforated door, beneath which is a tank lined with metal, in which a pipe is coiled, and from which the hot air or vapor to be employed radiates'. The case is provided with suitable ventilators to regulate the temperature, and sliding windows or panels,

through which the patient is reached, all of Which will hereinafter more fully appear.

In the drawings, Figure l represents a side elevation ot' my device. Fig. 2 is a front elevation, partly in section, to show the tank beneath the case. Fig. 3 is a plan. Fig. 4 is al planof Hoor.

The case A is composed mostly ot' glass sashes, and the top of it is provided with one or more ventilators or registers, b b, the slides of which can be moved so as to regulate the temperature of the bath.

The iioor c is grated and perforated with square, diamond, or other shaped openings d d, up through which the hot air or vapor passes from'the coil of pipe c, which is placed in the tank, f,.over which the glass case rests.

VThe tank is lined with Inetal, Vwith tight bottom and sides, so that no heat or, vapor can pass oif except at the top' through the grating and into the glass ease occupied by the pa- Vapor or hot air is admitted at the may be employed to shut o the source or supply of air or vapor.

The patient'occupies a -position on a stool or chair uponl the grate, Within easy reach of the ventilators b b at the top, by -means ot' which the temperature ofthe bath can be regulated.

Through the sliding panels lo the state ot' the pulse of the patient "may be ascertained, or stimulant or refreshments be 'passed to him, without materially lessening the temperature of the bath.

If a medicated vapor is required, it is administered by passing the apparatus through the panel or slide l.

A pipe, m, passing" through the frame-sash at the side of the door n, serves to admit air to thelungs of the occupant, which may be received through a iiexible tube and mouthpiece, o.

It should here be observed that by the use of this deviceabath is provided which is nonabsorbcnt, it being constructed mainly ot' glass, which Will resist the action ot' chemicals and moisture, that would naturally accumnlatev upon and penetrate a porous substance.

It will thus be clearly seen that should va` '-pors accumulate upon the inside of my bath, f

they can be easily removed by a cloth, and the bath be immediately prepared for another patient, who might desire adifferent treatment from that of the previous occupant.

The use of glass in constructing a bath is advantageous over metal for the reasons that glass will resist chemical actionv better than metal; and, also, it is desirable that the effect of the bath upon the patient may be seen by lthe attendant or physician administering the bath, which is the case in my apparatus. This is especially essential when a very sick or prostrated patient is being treated.

Having thus described my invention, what n I claim as new, and desire to secure by Letters Patent, is-

l. A chemical hot air orfvapor bath, constructed of glass, in the manner substantially as described and shown.

2. In combination the chamber A, construeted of glass, and the tank-f, placed be; In witness whereof I have hereunto set my 'low the same, substantially as described and hand andvseztl. shown.
